Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention secures a plate to a cooking vessel or the like having an exposed frame formed separately from a holding frame array so as to protect the edges of the plate and close the sides. And a cooking plate made of glass, vitreous ceramics or similar material with supporting legs of a holding frame arrangement attached to the lower edge of the plate.

[0002]

Cooking plates made of glass, vitreous ceramics or similar materials are associated with effective edge protection of plates that are extremely fragile at the edges of the cooking vessel and a cosmetically pleasing closure for cleaning. It requires a stable and easy-to-maintain mechanical holding (fixing) in the cooking container. This applies to mounting devices and stand devices and corresponding devices when used with the plates as heating or grill panels. In order to ensure the fixing, edge protection and lateral closure of the cooking plate, frame means are provided in a known manner for fitting the plate, which is formed in various ways according to the state of the art.

In the arrangement according to EP 162621, an annular angled metal has one leg forming a lateral closure and the other leg having an edge protrusion, ie a flange member for gripping the lower edge of the cooking plate. A frame member is provided. Further, the U-shaped member including the flange member and the space between the plate front face and the closing leg of the angle frame member are closely formed at the same height as the plate upper edge and the frame upper edge while ensuring edge protection. Then an annular packing is provided with an upright collar member. At that time, the cooking plate is attached to the joint between the collar member and the upper leg of the packing mold member and placed on the flange member.

When the lower leg of the mold member is bent downwards, the plate, together with the packing, moves away from the cooking vessel. At this time, the angle metal frame member is mechanically fixed to the cooking container by a conventional means.

In this type of construction, the holding or fixing of the plate as well as its edge protection and the lateral closure at the edge of the cooking vessel are realized by a single frame member. Therefore, there is a need for a frame member adapted for each implementation of the cooking panel. However, the market demands as much flexibility as possible in frame selection, which creates significant pricing and storage issues for cooking panel manufacturers.

Further, in the known cooking container provided with the one-member fitting frame, the fitting frame assembled to the stand range cannot be used as a mounting range frame at the same time, and conversely, the fitting frame assembled to the mounting range frame is at the same time. It has the drawback that it cannot be used as a stand range. Therefore, both the stand range and the mounting range sometimes require a new construction of the fitting frame, which requires additional and expensive manufacturing tools.

[0007] The same drawback has been found in West German Patent Publication No. 2819118.
It also occurs in a cooking frame structure according to the specification, which cooking frame structure is a single frame member composed (at least) of two different profiles without decomposition. The profile is formed so that on the one hand lateral closure is ensured with edge protection and the plate can be retained on the laterally projecting support web.

The support web is surrounded by a U-shaped joining plate and is attached to the joining plate. The joining plate is attached to the edge of the lower surface of the plate by its upper leg. The adhesive then fills the space between the front of the plate and the closing frame member, thus ensuring the necessary edge protection.

On the basis of the choice of material for the joining plate (for example special steel or aluminum) such as profiles, a very good mechanically firm connection with the cooking plate can be achieved. The (only one) frame member, together with the cooking plate, then forms a rigid unit which can be mechanically fixed in the usual manner to the cooking vessel.

Similar structures with a one-piece fitting frame are disclosed in West German Patent 3126013 and West German Utility Models 8624136 and 7718108. The above problems are caused by West German Patent No. 31.
No. 26013 and West German Utility Model No. 7719859
It is solved by the two-part frame construction of the cooking plate according to the specification. This structure has a holding frame or fixed frame with supporting legs for the lower edge of the cooking plate, to which the cooking plate is attached (West German patent specification) or to the supporting leg. The packing plate places the packing in an intermediate position (West German utility model specification).

Apart from that, there is an exposed or sealing frame which ensures edge protection and forms a lateral closure. At that time, the holding frame and the exposure frame are detachably coupled to each other and mechanically fixed to the cooking container in a usual manner.
According to the principle of disassembling the inset frame, a damaged or dirty exposure frame is replaced with a new one, and at the option of the same cooking device at least one of the exposure frame of a different color and the exposure frame of a different mold shape is retained. Can be combined with
Great flexibility is provided in the selection of the frame in a simple and inexpensive way.

Furthermore, the fitting frame can be flexibly adapted to the stand range as well as the mounting range during the widest standardization. Thus, this two-piece construction of the inset frame allows the glass to be easily and flexibly adapted to different production requirements when using the most extensively standardized frame mounting members.
Enables a preferred frame unit system for cooking plates made of glassy ceramics or similar materials, in particular stand range and mounting cookers as edging / edge protection of cooking panels and as basic elements for accommodating / fixing other cooking ingredients Enables a frame unit system to be inserted into a panel. At that time, the frame unit method is very flexible, simple, and extremely flexible when holding the frame mounting member and other components (heating element, residual heat indicator, etc.) in the widest possible range. It can meet different requirements in a price-friendly way.

[0013]

To attach the glass or glassy ceramic plate to the supporting leg of the holding frame requires special know-how regarding the material selection and the bonding technique which is beyond the control of the manufacturer of the cooking apparatus. To do. In this case, the known holding frame, which extends relatively long and forms the cooking panel side wall in this case, has to be applied by the manufacturer of the cooking plate, so that a very bulky and expensive packaging is required. And result in a very bulky product. The object of the invention is therefore to start from the cooking plate and to configure the cooking plate in such a way that the support legs can be reliably attached to the plate without producing bulky goods.

[0014]

According to the invention, the solution to this problem is formed in such a way that the supporting legs of the holding frame arrangement (10) detachably accommodate the supporting parts (supporting members 11) of the holding frame arrangement. Formwork of slight height (10a; 10b;
10c). A first advantage of the present invention is the savings in shipping volume in shipping.

In the case of the cooking plate according to the present invention, it suffices that it is packaged by a narrow formwork to which the plate is attached. The usual elements of the holding frame can only be inserted into the profile by the cooking vessel manufacturer.

Another advantage resides in that only the formwork to which the cooking panel can be applied has to be manufactured from special steel. The other components of the undercarriage can consist of simple and cheap sheet steel (not suitable for pasting). That can save a lot of money.

To detachably accommodate the support members in the formwork, any coupling technique known to those skilled in the art can be used. In particular, the preferred and simple construction is achieved in that the receiving ends of the support member and the form are designed such that they can be mechanically connected to one another by a bayonet connection.

With regard to the formwork, the expert is left with a series of possibilities. A particularly simple joining technique is achieved by the formwork having a U-shaped cross-section, one leg of which forms the support leg, in which case the flange of the support member can be inserted into the U-shaped material. To be done. At that time, in the embodiment, the U-shaped member is adapted to be opened and attached on the front surface of the plate.

In the embodiment, the U-shaped member is opened and attached at the center of the plate, and the outer surface of the column base is closed at the same height as the front face of the plate. Both of these possibilities open up various possibilities of fixing the holding frame to the cooking vessel. At that time, it is purposeful that the formwork is attached at the same height as the front surface of the plate in each case.

The legs of the U-shaped formwork in cross section must not necessarily run parallel to each other. The legs start from a column base with a U-shaped cross section and extend rather divergently, with the free lower leg forming an acute angle with the upper leg attached to the plate. The lower leg may be folded down at its front end to form a wide insertion opening for the flange of the retaining member.

The formwork is an annular member, but may be formed in multiple parts. In particular, the frame consists of a number of parts which are arranged in a divided manner around the perimeter of the plate.

A series of configurations is possible for the exposure frame.
The exposed frame has a cover collar bent to close the upper end of the intermediate web, the collar being formed in different ways and associated with the cooking plate or range wall or workbench in the mounting container in different ways and ways. The configuration is particularly preferable. Preferred configurations are described in the dependent claims.

The invention will be explained in more detail on the basis of the embodiments illustrated in the drawings. In doing so, other features and advantages of the invention become apparent.

[0024]

[Example] FIG. 1 shows a cooking vessel 1 of a mounting range which is mounted on a workbench 80. The cooking vessel has a cooking panel in the form of a glassy ceramic plate 30. Glass plates or plates of similar material can be used in a known manner for cooking panels of this kind. The cooking vessel is bounded inward by a cooking vessel housing, the elements of which are described further below.

In order to hold the vitreous ceramic plate 30 and protect the plate edge thereof, a two-member fitting frame composed of a holding frame, that is, a fixed frame 10 and an exposure frame 20 is used. The holding frame 10 is C-shaped in cross section and comprises an intermediate web 11 forming the side wall of an upright cooking container housing. Further, the fixed frame 10 has a horizontal U-shape and has a bent upper coupling flange 12 to be inserted into the mold 10a. This side frame is joined to the lower edge of the vitreous ceramics plate 30 by means of an adhesive layer 60 by means of a mold upper leg which forms a support leg for the cooking plate 30.

This bayonet connection is particularly apparent from the enlarged sectional view according to FIG. Bent lower coupling flange 13
The holding frame 10 is screwed to the floor plate 40 of the cooking container howbing via the. A heating element for a cooking panel is arranged on the floor plate 40, and only a housing 41 is shown for simplification of the heating element. Furthermore, the floor board 40
Other ingredients such as a preheat indicator are placed in the usual manner. The coupling flange 13 is further joined to a housing member 40a below the floor plate 40, which housing member is the floor member of the cooking vessel housing.

The exposed frame 20 has an intermediate web 21 upright in the mounting position in the profile, the (annular) wall formed thereby enclosing the side wall formed by the intermediate web 11 of the holding frame 10 with almost no play. And thus both frame members 1
Since the 0 and 20 positions are fixed, both parts can easily be screwed together. With the upper end of the intermediate web 21 closed, the exposed frame 20 has a cover collar 22 bent inward, which collar 22 is a vitreous ceramic plate 3.
The upper edge of 0 is covered thereby forming a closure.

The exposure frame 20 envisioned in the mounting range according to FIG. 1 additionally closes off the upper end of the intermediate web 21 and provides an outwardly bent covering collar 23 which forms a closure with the workbench 80. Have. The covering collars 22 and 23 serve, on the one hand, for edge protection of the cooking plate 30 and, on the other hand, form a closure on the plate upper edge as well as on the workbench.

As can be seen from FIG. 1, the intermediate web 21 of the exposed frame projects somewhat above the upper edge of the cooking plate 30, with both coating collars being respectively beveled with respect to the surface of the cooking plate or the workbench. It has been folded into. Some feasibility of forming a coating collar will be further explained later (FIG. 8).

Unlike FIG. 1, FIG. 2 shows a cooking vessel 1 mounted on a stand range, which cooking vessel also has a two-part fitting frame made up of a holding frame 10 and an exposure frame 20. The holding frame 10 is inserted into the mold 10a attached to the cooking plate by its flange 12 corresponding to the cooking container 1 according to FIG.

Comparing both figures with respect to the holding frame 10, it can be seen that both frames are identical. The holding frame 10 is therefore unchanged for all embodiments of the range and is therefore a standardized component. Merely the exposed frame 20 must be adapted to the various embodiments of the range.

The exposed frame 20 constructed in the stand range according to FIG. 2 forms a clear upper fancy dress which is held together in shape. Moreover, the lower leg 25 of the exposure frame 20 is engaged with the hook 90 of the apparent lower range temporary dressing 25a, and the lower temporary dressing 25a is further screwed to the holding frame 10. For reasons of assembly, the exposure frame 20 can be screwed together 4
It consists of individual side members.

Therefore, the exposure frame 20 is directly connected to the holding frame 10.
2, the exposed frame 20 is indirectly connected to the holding frame 10 via the hook 90 of the lower temporary dressing 25a. The exposed frame 20 of FIG. 2 further has a covering collar 22 which is closed at the upper end of the intermediate web and is folded into a cooking plate 30, the detailed construction of which is explained further below in comparison ( (Figure 9).

1 and 2, the fitting frame members 10 and 2 are shown.
0 indicates a predetermined embodiment in which 0 is overlapped with each other and is connected to the floor plate 40, the floor member 40a, or the range wall 25a (in the case of FIG. 2). Here, the set of possibilities is left to the expert. Therefore, for example, in the case of FIG. 1, it is conceivable that the intermediate web 21 of the exposed frame is pulled down to the floor of the cooking container and is coupled there with the holding frame or the floor member 40a.

In the embodiment according to FIGS. 1 and 2, the U-frame is open at the rim of the cooking vessel. It can be attached by shifting it by 180 degrees so that the U-shaped opening faces the center of the plate. This aspect allows various fixings to the cooking container.

3 and 4 show a fitting frame which can be easily cleaned in consideration of hygiene. In this case, the exposure frame 2
0 and the side edge of the vitreous ceramic plate 30 have an annular packing 50, whose packing surface joins the upper edge of the vitreous ceramic plate 30 to the same height as the inner upper edge of the exposed frame 20. The detailed configuration will be further described later by comparison (FIGS. 11 and 12).

In the embodiment according to FIG. 3, ie in an attached cooking vessel, the covering collar 23 is attached to the plate surface and the workbench 8.
It is bent at the same height as 0, and on the other hand,
In the case of, that is, in the stand range, the exposure frame 20
The coating collar 22 of the first is at the same height as the plate surface,
Then, before reaching the edge of the plate, it is bent again at a right angle downward. This results in a smooth, flat surface that can be easily cleaned.

U-shaped frame 1 attached to the lower surface of the plate
Details of the bayonet connection between 0a and the connecting flange 12 of the support member 11 of the holding frame 10 are likewise apparent from FIG. A series of known possibilities for packing 50 are left to the expert. Thus, for example, a suitable adhesive may be used to make the annular packing.

In the case of the bayonet connection according to FIG. 5, the legs of the U-shaped frame 10a run exactly parallel to each other. FIG. 6 shows an embodiment in which the lower leg comprises a form 10b which is inclined to open the U-section, in which case in order to achieve a positive profile in the bayonet connection, the holding frame 10
The coupling flanges 12 of the support members 11 of 1 should be formed in conformity.

FIG. 7 suitably shows an embodiment of the bayonet connection according to FIG. 5, which comprises a formwork 10c whose lower legs are inclined to partially open the U-section. In this case too, the coupling flange 12 of the support member should conform to its shape. The embodiment according to FIGS. 6 and 7, like the embodiment of FIG. 5, is limited to certain embodiments of the cooking panel or its associated exposure frame.

In the illustrated embodiment according to FIGS. 5-7, the ends of the legs are formed flush with the front of the plate 30, since the molds 10a, 10b, 10c are attached to the plate. The arrangement is such that the profile post connects to the front of the plate, ie the profile opens the interior of the plate (on the right in the figure).

The molds 10a, 10b, 10c can be formed as a one-piece frame that completely covers the periphery of the cooking plate 30. If cooking panel construction or such requirements are required, the formwork may consist entirely of the perimeter of the cooking plate 30 or may be divided along the perimeter of the plate and spaced apart for attachment.

As already shown in the comparison of FIGS. 1 to 4 with one another, for the formation of the covering collars 22, 23 of the exposure frame 20, a number of configurations are possible, which shall be explained briefly on the basis of the following figures. These alternatives can be used selectively in the unit system or in individual embodiments from the exposure frame to the plate. In the case of these consecutive figures also, the same parts are provided with the same reference numerals, and in this case, mainly for the sake of simplification, only different states are given reference numerals.

In FIGS. 8A to 8D, the exposed frame is the intermediate web 2.
Figure 1 shows an (enlarged) cross-section of the cooking stove for a stove according to Figure 1 with the covering collar 22 bent to the ceramic plate 30 with the upper end closed and the covering collar 23 bent away from the plate. The covering collars 22 and 23 then extend in a slanted manner on the plate surface or on the cooking panel border.

In the simplest case of FIG. 8A, the beveled end of the coating collar 22 simply rests on the plate surface without packing tape or additional adhesive. This allows easy and quick assembly or disassembly on one side, while eliminating the requirements on waterproofness and hygiene on the other side. During assembly, unacceptable stresses will occur on the cooking panel (tolerance, frame and cooking panel).

The embodiment according to FIG. 8B comprises a packing tape 51 between the cooking plate and the covering collar. Although this embodiment is hygienic and waterproof, it does require additional assembly work on the style of packing adhesive tape. The above-mentioned unacceptable stresses will occur on the cooking panel during assembly.

The embodiment according to FIG. 8C comprises an annular adhesive packing 53 which fills the space under the coating collar at the height of the plate edge. This configuration is waterproof, stress-free, and leaves health and hygiene requirements in mind.
This is because foreign matter enters the space below the slope of the covering collar 22 that can no longer be removed.

The embodiment according to FIG. 8D is finally provided with an annular adhesive packing 52 which fills the space under the covering collar 22 and between the intermediate web 21 and the side edges of the plate.
Examples of this kind are waterproof, hygienic,
Although stress-free, assembly and disassembly is quite expensive.

FIG. 9 shows an embodiment of the construction of the covering collar 22 of the exposed frame in the stand range with different sub-regulations in the transverse area to the cooking plate 30.
Again, only the important elements are shown or provided with reference numbers.

In the embodiment according to FIG. 9, the intermediate web 21 of the exposed frame projects somewhat from the upper edge of the plate, and the covering collar 22 connected to the upper edge of the plate is bent at the end on the surface of the plate 30 in a beveled shape. Has been done. This embodiment has already been illustrated in many facts in FIG.
Also shown in FIG. 9 are various aspects consistent with FIG. 8 with direct contact between aspect 9A of packing 51 located therebetween.
(Aspect 9B), the edge packing 53 according to Aspect 9C,
A packing 52 is provided which completely encloses the plate conforming to aspect D.

In FIGS. 8 and 9, the edge area of the cooking vessel is shown in an idealized cross-section, in each case the covering collar 22 covers the glassy ceramic plate. 10 to 11
Shows a similar cross-section, but without a cover of this kind. The same elements in these figures have the same reference numbers. 10 and 11 show an embodiment of the attached cooking vessel (see also FIG. 3), while FIG. 12 shows such an embodiment of the stand range (see also FIG. 3).

The common feature is that in each case the adhesive seam, which is applied later between the front face of the ceramic plate 30 and the intermediate web 21 of the exposed frame 20, is stretch-resistant and heat-resistant (for example silicone). Adhesive) is applied appropriately. This type of construction is particularly highly water resistant, stress-free and hygienic.

In the embodiment according to FIG. 10, the covering collar 23 is bent at the ends, whereas in the embodiment according to FIG. 11 the covering collar 23 is consistent in a given mounting relationship. It is flat and extends horizontally. In the case of the mounting range according to FIG. 12, the covering collar 22 of the exposed frame is folded down once again before reaching the plate edge, so that the part between the intermediate web 21 and the covering collar 22 is approximately the plate surface. It is the same height.
